Subject: [PATCH] Preserve PATH variable when using sudo

Some systems set `secure_path` in sudoers. When this is set
the `PATH` variable is not set in the sudo environment. Using
`--preserve-env=PATH` ensures that the PATH env var is set properly
in those systems.

This is similar to the issue with [darwin-rebuild](https://github.com/nix-darwin/nix-darwin/issues/798)
not working with sudo on these systems.
